Overview
The TS4900ID is a mono Class AB audio power amplifier manufactured by STMicroelectronics. It delivers 700mW of output power into an 8-ohm load at a 5V supply voltage. The device operates within a supply voltage range of 2.6V to 5.5V and features a gain bandwidth product of 2MHz. It includes integrated Depop, Standby, and thermal protection circuits. The component is housed in an 8-pin SOIC package and supports operation temperatures from -40°C to 85°C.
Feature Summary
- Integrated Depop circuitry to eliminate speaker popping during power transitions
- Built-in standby mode for reduced power consumption when inactive
- Thermal protection mechanism to safeguard against overheating conditions
Applications
- Portable audio devices requiring low-power amplification
- Mono audio channels in consumer electronics
- Battery-operated sound systems
Procurement Notes
Verify the specific suffix (ID) confirms the SOIC-8 package and industrial temperature range. Confirm RoHS compliance status as some sources indicate lead-containing variants exist. Ensure the ordering code matches the exact pinout and electrical specifications required for the design. Cross-reference with official STMicroelectronics documentation to validate current production status and availability.
Selection Notes
Select this component for mono audio applications where moderate power output is sufficient. Consider the 2.6V minimum operating voltage for battery-powered designs. Evaluate the need for external components versus the internal protection features. Compare performance metrics against other Class AB amplifiers if higher fidelity or stereo capability is required.
Part Context
This part belongs to the TS4900 series of audio power amplifiers from STMicroelectronics. The series focuses on providing high audio quality with efficient power usage. The TS4900ID variant specifically denotes the industrial temperature grade and surface-mount packaging configuration suitable for automated assembly processes.
Replacement Considerations
Check for direct substitutes such as the TS4900LDT for tape-and-reel packaging. Verify compatibility with existing PCB footprints and thermal management requirements when switching between package types.
